Kl. Lee et C. Shu, Alternate and simultaneous generation of 1-GHz dual-wavelength pulses froman electrically tunable harmonically mode-locked fiber laser, IEEE PHOTON, 12(6), 2000, pp. 624-626
A new scheme of producing dual-wavelength mode-locked pulses from a fiber l
aser is proposed and experimentally demonstrated. In addition to the simult
aneous generation of two selected wavelength components, the scheme also al
lows the alternate generation of mode-locked pulses at different wavelength
s. The alternate switching of wavelengths is demonstrated at 1 GHz, and has
been achieved over an electrical tuning range of 13.1 nm using the dispers
ion-tuning approach. A constant mode spacing of 7.1 nm is maintained during
the tuning process.
